A penalty approach to differential item functioning in Rasch models.
A new diagnostic tool for the identification of differential item functioning (DIF) is proposed. Classical approaches to DIF allow to consider only few subpopulations like ethnic groups when investigating if the solution of items depends on the membership to a subpopulation. We propose an explicit model for differential item functioning that includes a set of variables, containing metric as wel...
متن کاملGender bias in the sixteen-item Anxiety Sensitivity Index: an application of polytomous differential item functioning.
Gender differences in measures of anxiety sensitivity (AS) are similar to gender differences across anxiety disorders; females exhibit higher levels of AS and a greater prevalence of anxiety disorders than males. The current study confirms higher scores on the Anxiety Sensitivity Index (ASI) in females. Further analysis reveals, however, that gender differences on the ASI may arise from a singl...
متن کاملA confirmatory study of Differential Item Functioning on EFL reading comprehension
The present study aimed at investigating DIF sources on an EFL reading comprehension test. Accordingly, 2 DIF detection methods, logistic regression (LR) and item response theory (IRT), were used to flag emergent DIF of 203 (110 females & 93 males) Iranian EFL examinees’ performance on a reading comprehension test. Seven hypothetical DIF sources were examin...
متن کاملTest bias in a cognitive test: differential item functioning in the CASI.
Assessment of test bias is important to establish the construct validity of tests. Assessment of differential item functioning (DIF) is an important first step in this process. DIF is present when examinees from different groups have differing probabilities of success on an item, after controlling for overall ability level. Here, we present analysis of DIF in the Cognitive Assessment Screening ...
متن کاملUsing differential item functioning to evaluate potential bias in a high stakes postgraduate knowledge based assessment
BACKGROUND Fairness is a critical component of defensible assessment. Candidates should perform according to ability without influence from background characteristics such as ethnicity or sex. However, performance differs by candidate background in many assessment environments. Many potential causes of such differences exist, and examinations must be routinely analysed to ensure they do not pre...
